Good numbers? (hd power on \ ssd writes \ OS install)

[6730b]

My trusted old Dell E7440, 7+ years with the samsung 256 GB msata, 5 years with the Seagate 2 TB.
Am always amazed by the longevity of most electronics.

& still on the original win 8.1 install (open shell + a few tweaks). 7+ great years, superstable OS .
Will miss it when execution date of OS arrives... If the 7440 is still in use, it'll get 10 ltsc.

Nice.

 

Drives in my M6700, for some sort of comparison & indication as to how many host writes you need before the "health" starts to go down 😛 .  M6700 is nearly ten years old but the drives are not as old as that.  (Also I tend to leave them on 24/7, as indicated by my low "power on count" compared to yours.)  QVO is the "youngest" at 3+ years and mSATA is the "oldest" at 5.5 years.

160TB writes on that 1TB drive, impressive!

Thanks for showing those great numbers ! Even the 'antique' msata good as new after 60+TB.
Remembering the early days, people panicking that ssd's lifespan would evaporate in a few days or so if put to any kind of normal use :O)

About the (surely unusual) large startup counts on the e7440, it's type of use implies lots of sleep\hibernate every day, year after year.

Yeah, I remember people also flipping out over Samsung QVO which had about half of the endurance as EVO at the time that it launched.  "You shouldn't buy one of these drives, it will fail way too soon!"

 

Think for a second and run some numbers...

The Samsung 860 QVO 1TB model is rated for 360 TBW.

To hit that within three years (the warranty period), you'd have to average 336 GB of writes per day every day for the entire three years.  That's replacing about one third of the contents of the drive every day.

 

That's something that an ordinary user will never do.  Sure, there could be days when you download something large, do some data shuffling, or reinstall Windows and have a few hundreds of GB written.  But sustaining that day after day after day?  Crazy stuff.

 

You can do a similar check with any SSD and the numbers will probably be even better than this QVO which has a relatively low TBW rating.  My Samsung 860 EVO 1TB (160 TB written, according to the screenshot above) is rated for 600 TBW.  Not even close to hitting it.

 

The TBW rating is not a hard cutoff either, it's just what the manufacturer is willing to commit to for purposes of warranty.  Testing has shown that drives normally last well beyond that.

I have a few SSDs in my main system. I have a few others, might post pics of my other SSDs when I'm not lazy. Also anyone know how to view stats on M.2 SSDs?

I use Windows 7, and I can say that you don't need to worry about that.

They just show up in CrystalDiskInfo for me on Windows 10, just like the SATA drives.  Maybe since Windows 7 needs a third-party NVMe driver, CrystalDiskInfo can't find them...?

Windows 7 (with update), 8.1, and 10 all use the same NVMe driver. That shouldn't matter.

any stats that dont show up on crystaldiskinfo can usually be read out using the SSD specific tool box from the SSD manufacturer. also ensure that ure on the latest crystaldiskinfo version 🙂

WD software doesn't support 7, and I'm not sure where I can find a version that works on 7.
